| ［摘要］ 随着血管腔内治疗器材的不断创新，腔内治疗已逐渐成为下肢动脉狭窄闭塞性疾病的主要治疗模式。由于股腘动脉具有特殊的生物力学特点，即便是最新一代的镍钛合金支架，其远期通畅率仍不理想。由于药物涂层技术在抑制下肢动脉内膜过度增生中的作用，载药器械逐渐成为髙级别临床应用的推荐，尤其适合股腘动脉长段病变、钙化病变、再狭窄病变及膝下病变等。理想的血管准备包括减容手段的合理应用以及球囊扩张模式优化等，可进一步避免或减少球囊扩张或支架植入后的血管再狭窄和再干预率，因此下肢动脉应规范血管腔内治疗，严格把握适应证，在实践和创新中切实提高疗效。 |

| Abstract: |
| ［Abstract］ With the continuous innovation of endovascular treatment equipment, endovascular treatment has gradually become the main treatment mode for arterial stenosis and occlusion diseases of lower limbs. Due to the biomechanical characteristics of the femoral-popliteal artery in its special parts, the long-term patency rate is still unsatisfactory even for the latest generation of nickel-titanium alloy stents. In view of the role of drug coating technology in inhibiting intimal hyperplasia of lower limb arteries, drug-carrying devices have gradually become recommendations for high-level clinical applications, especially suitable for long-segment lesions of femoral-popliteal artery, calcified lesions, restenosis lesions and infrapatellar lesions. Moreover, ideal vascular preparation includes reasonable application of volume reduction measures and optimization of balloon dilation mode, which can further avoid vascular restenosis after balloon dilation or stent implantation or reduce the re-intervention rate. Therefore, endovascular treatment of lower extremity artery should be standardized,and the indications should be strictly controlled, and curative effect should be effectively improved in practice and innovation. |
